I was just locked out of my own WP site by another security plugin that I used. It kept locking me out everytime I tried a password reset.
Finally a friend suggested Better WP Security and once I installed it, I realized just how much better it is then ANYTHING else out there.
This is simply the BEST WP security plugin that you can get.
Don't even wait, deactivate your other plugins and use Better WP Security.
You won't be disappointed.
